ABSTRACT

We studied 40 patients with Ebstein anomaly with atrioventricular reentrant tachycardia and at least one accessory pathway. We found one accessory pathway in 23 (57.5%) patients and multiple accessory pathways in 17 (42.5%). Mahaim accessory pathway was observed in 6 (15%) patients. A total of 61 accessory pathways was found, of them 6 (9.8%) were concealed and 55 (90%) manifest. In 59 (96.7%) the accessory pathways were located in the tricuspid ring. The most frequent regions were the right posteroseptal with 18 (29.5%) and right lateral free wall with 16 (26.2%). The patients were underwent radiofrequency catheter ablation via femoral vein in 30 and via trans-surgical ablation in 10. The successful primary rate was 71.7% in radiofrequency catheter ablation via femoral vein and 100% via trans-surgical ablation. No complications were observed during the procedures. In conclusion, radiofrequency catheter ablation via femoral vein is the treatment of choice in patients with Ebstein anomaly without deteriorated hemodynamic state. Radiofrequency catether ablation in patients with Ebstein anomaly is both safe and effective.
